Thomas & Betts LTBUS07L-C LFMC CMP UL 2IN BLU 30M/100FT

It's 2 inch trade size liquid tight flexible metallic conduit, supplied in a 100 ft (30 m) coil. One coil covers a single 100 foot run or several shorter drops, so figure your total footage plus slack at each termination before ordering quantity.

That's what liquidtight flexible metallic conduit is built for. The galvanized steel core takes the mechanical abuse and the jacket keeps water out of the raceway, which is why LFMC is the standard choice for the last few feet into a motor, pump, compressor or rooftop unit where vibration and weather both come into play.

Blue jacket is the color-coding convention used to keep a circuit type visually separate on a job, and this run of LFMC is jacketed in blue. Electrically and mechanically it is the same construction as any other jacket color: galvanized steel core under a liquidtight jacket. Pick the color that matches how the facility identifies its circuits.

Use rigid or EMT for the long, fixed portion of a run and switch to liquidtight flex only where you need movement or vibration isolation, typically the final connection to rotating or vibrating equipment. This 2 inch LFMC is the flexible piece of that assembly, not a substitute for a full rigid raceway. If the location is dry and indoors and there's no vibration, plain flexible metal conduit without the liquidtight jacket is the cheaper answer.

The core is galvanized steel, which is what gives this conduit its physical strength and crush resistance. In 2 inch trade size, standard practice is to pull a separate equipment grounding conductor rather than relying on the flex itself for the fault current path, especially on a vibrating equipment connection. Size the EGC to the circuit's overcurrent protection.

Order Thomas & Betts LTBUS07L-C. That number covers the 2 inch blue liquidtight flexible metallic conduit in the 100 ft coil, so it's the one to quote for a matching reorder.
